With all the tents (where did they come from? who provided them?) around OccupyHK, how do you know which are available

With all the #tents (where did they come from? who provided them?) around #OccupyHK, how do you know which are available and which are in use? Some protesters have come up with occupied / vacant signs to put on the #tent. Actually, I think they should have done this sooner. Anyone up for some urban camping? Just find a vacant tent! #HongKong #hk #hkig
